I am currently trying to buy Macbook pro retina 13' which is around $1399 + tax. I know that last year during mid July Bestbuy and Amazon held their back to school sale for Macbook, which was $300 discount for Macbook pro. But I live in GA (also very close to SC) and tax free weekend is on first week of Aug. I am not sure if apple store would do back to school promotion but I can save tax if I buy Macbook on SC. Finally, I believe apple annually markdown price of their products as new lines come out on September. Since I am trying to buy Macbook pro 13' retina version, there is high chance of price markdown for the specific model. I have been pc user until now, so I am very confused when to buy macbook. Please help me and give me some insight to buy Macbook at affordable price!! I really appreciate your help and attention.
